When the mercury plummets faster than the fresh flakes fall, suit up in the Men's Peak Performance Heli Loft Jacket and stay on the hill long after your crew has gone to hide in the lodge. The Gore Tex shell combines with ThermoCool insulation to keep you dry and warm while the articulated sleeves ensure total freedom of movement. Gore Tex Performance Shell fabric is guaranteed waterproof and breathable to keep moisture out while allowing vapor to escape, so you stay dry from the inside and out. A healthy dose of low profile, lightweight Thermacool insulation in the body helps you stay toasty without weighing you down or making the jacket too puffy. Mesh lined underarm vents allow you to dump heat on long hikes and sunny spring days, while the Snap in system lets you hook up your jacket to your Peak Performance pants to seal out snow on deep days. The regular fit leaves room to layer underneath without being too baggy and a drop hem keeps your butt dry when you're sitting on the chair.
